description
The SN65LBC176A, SN65LBC176AQ, and
SN75LBC176A differential bus transceivers are
monolithic, integrated circuits designed for
bidirectional data communication on multipoint
bus-transmission lines. They are designed for
balanced transmission lines and are compatible
with ANSI standard TIA/EIA-485-A and ISO 8482.
The A version offers improved switching perfor-
mance over its predecessors without sacrificing
significantly more power.
